Description

The GLEAMS model pesticide component was modified to simulate up to 245 pesticides simultaneously, and the revised model was used to pesticide pesticide application windows for forest site preparation and pine release. Five herbicides were made for soils representing four hydrologic soil groups in four climatic regions of the southeastern United States. Five herbicides commonly used in the region to control compating vegetatfon wore representqd in the model study. Within the application windows for each herbicide, the best application dates, or environmental windows were determined to minimize environmental effects for each location. Results of the simulation study are tabulated in the paper for use in the forest industry.
